RS Series are available in 8, 12, and 16 channel models, each with either 1, 2 or 3 isolated outputs. Ground lift switches are provided for each channel.

Each microphone splitter features a 1:1, 1:1:1, or 1:1:1:1 turns ratio bridging transformer with a single primary and one, two, or three secondary windings. Transformers also maintain separate faraday shields and reject common mode noise caused by the voltage differences between the chassis of the multiple mixers. Phantom power can be passed through the direct output.
